Prepare the cupcake batter. Take softened butter and sugar and beat with a mixer or whisk. Add vanilla sugar and continue beating. Beat eggs into the batter one by one and stir. You should get a light, foamy mass.
Sift flour with salt and baking powder. Pour half of the flour mixture into the main mass and mix thoroughly. Pour in milk, stir, add the remaining flour mixture. Mix everything until smooth.
Prepare the oven and cupcake pans. Preheat the oven to 170 degrees. Spoon the batter into the pans, one tablespoon into each. Place the pan in the oven and bake for 20 minutes. Let the cupcakes cool.
Prepare the cream. Take three egg whites. They should be cooled. Add sugar, place in a double boiler and beat until fluffy. Remove the bowl from the boiler and continue beating the cream until it cools completely. Add soft butter to the egg whites in small portions and beat until smooth. Add vanilla extract and food coloring. Mix again.
Decorate cupcakes with cream. To do this, put cream in a pastry bag and squeeze it onto the cupcakes in the shape of beautiful caps.
